BACKGROUND:Surgical options for pathology affecting the long head of the biceps tendon (LHBT) include tenotomy and tenodesis, both of which can be performed with a variety of fixation methods. This study aimed to compare surgical treatment options for LHBT lesions using a network meta-analysis of published clinical studies. METHODS:A systematic review of the literature was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Clinical studies comparing surgical treatment options for LHBT lesions were included. Postoperative outcomes were compared between surgical treatment options using a frequentist approach to network meta-analysis. RESULTS:There were 22 studies comparing surgical treatment options for LHBT pathology including arthroscopic tenotomy, arthroscopic suprapectoral tenodesis, arthroscopic intracuff tenodesis, and open subpectoral tenodesis, consisting of 1804 patients. Compared with arthroscopic tenotomy, open subpectoral tenodesis resulted in a significantly greater American Shoulder and Elbow Surgeons score (mean difference, 4.58; P = .014). On the basis of the P-score, all 3 tenodesis techniques ranked above tenotomy with respect to the Constant score. Compared with arthroscopic tenotomy, the incidence of Popeye deformity was reduced with arthroscopic suprapectoral tenodesis (odds ratio [OR], 0.23; P < .001) and open subpectoral tenodesis (OR, 0.25; P = .022). The incidence of bicipital groove pain was increased after arthroscopic intracuff tenodesis (OR, 2.89; P = .021) compared with arthroscopic tenotomy. CONCLUSION/CONCLUSIONS:Lesions of the LHBT treated with open or arthroscopic tenodesis resulted in comparatively superior functional outcomes and a lower incidence of Popeye deformity, whereas arthroscopic intracuff tenodesis resulted in a higher incidence of bicipital groove pain.

BACKGROUND:Given the relatively low incidence of infection, the role of prophylactic antibiotics for infection prevention in arthroscopic surgery is unclear. Without established evidence-based guidelines, it becomes important to understand the trends and common practices in the field. HYPOTHESIS/OBJECTIVE:We hypothesized that a majority of surgeons would use preoperative intravenous antibiotics and that postoperative antibiotics would be rarely used. METHODS:A web-based link containing a questionnaire on perioperative antibiotic use for arthroscopic surgery of the knee and shoulder was sent to sports medicine surgeons at several institutions in the New York tri-state region. The questionnaire addressed antibiotic use both preoperatively and postoperatively and the type of medication used. RESULTS:During the study period, 86 surgeons responded to the knee portion of the survey and 139 surgeons responded to the shoulder portion of the survey. A significant majority (94.24% for knee and 93.02% for shoulder) of the respondents routinely preferred to use preoperative intravenous antibiotics for both shoulder and knee surgery. The antibiotic of choice for a majority of the respondents was cefazolin (98.1% respondents). In patients with penicillin allergies, most preferred to use clindamycin. Most respondents (84.5%) did not routinely use postoperative oral antibiotics. CONCLUSION/CONCLUSIONS:There is significant consensus among orthopedic surgeons performing knee and shoulder arthroscopic surgery regarding use of preoperative antibiotics, with the majority routinely prescribing preoperative intravenous antibiotics for prophylaxis and cefazolin being the most commonly used antibiotic. The majority of surgeons prefer not to use postoperative oral antibiotics. CLINICAL RELEVANCE/CONCLUSIONS:This study describes the current trends in the use of perioperative antibiotics among orthopedic surgeons for routine arthroscopic procedures in the shoulder and knee.

Suprascapular neuropathy is a potential source of shoulder pain and functional limitation that can present secondary to various etiologies including entrapment or compression. Cystic lesions arising from a labral or capsular tear can compress the nerve along its course over the scapula. Nerve traction is theorized to arise from chronic overhead athletics or due to a retracted rotator cuff tear. The diagnosis of suprascapular neuropathy is based on a combination of a detailed history, a comprehensive physical examination, imaging, and electrodiagnostic studies. Although the anatomic course and variations in bony constraint are well understood, the role of surgical treatment in cases of suprascapular neuropathy is less clear. Recent reviews on the topic have shed light on the outcomes after the treatment of suprascapular neuropathy because of compression, showing that surgical release can improve return to play in well-indicated patients. The incidence of compressive neuropathy is quite high in the overhead athletic cohort, but most patients do not show clinically relevant deficiencies in function. Surgical release is therefore not routinely recommended unless patients with pain or deficits in strength fail appropriate nonsurgical treatment.

BACKGROUND:There has been a recent surge in health-care providers offering stem cell therapy (SCT) to patients with musculoskeletal disease. The purpose of this study was to identify and quantify the misinformation present in online direct-to-consumer (DTC) advertising of SCT targeting patients with musculoskeletal disease in the U.S. It was hypothesized that DTC advertising of SCT contains substantial misinformation. METHODS:A list of keywords was used to identify web sites of practices advertising SCT directly to patients with musculoskeletal disease. Web sites were evaluated to determine the specialties of providers offering SCT, types of SCT being advertised, and misinformation presented. Categories of misinformation included false general claims, inaccurate statements regarding mechanism of action, unfounded results, and scare tactics. RESULTS:Of the 896 practice web sites included in the analysis, 95.9% contained at least 1 statement of misinformation, with a mean of 4.65 ± 3.66 statements of misinformation among the sites. Practices associated with an orthopaedic surgeon provided 22% fewer statements of misinformation than practices without an orthopaedic surgeon when we controlled for the effects of other specialties. Practices associated with a podiatrist also provided 22% fewer statements of misinformation. CONCLUSIONS:Nearly all practices failed to accurately represent the clinical efficacy of SCT in DTC advertising. While practices associated with an orthopaedic surgeon were less likely to provide misinformation, the majority of all web sites contained some type of misinformation, ranging from errors in the basic science of stem cells to outright false and misleading claims of their clinical effectiveness.

Meniscus surgery has dramatically changed over the last 20 years. This article reviews the advances and current evidence in meniscus repair.

OBJECTIVE:The purpose of this study is to systematically review the literature and to evaluate the reported rehabilitation protocols, return-to-play guidelines, and subsequent rates of return to play following cartilage restoration procedures in the knee. DESIGN/METHODS:MEDLINE, EMBASE, and the Cochrane Library were searched according to the PRISMA guidelines to find studies on cartilage restoration procedures in the knee, including (1) microfracture (Mfx), (2) osteochondral autograft transfer (AOT), (3) osteochondral allograft implantation (OCA), and (4) autologous chondrocyte implantation (ACI). Studies were included if they reported return-to-play data or rehabilitation protocols. RESULTS:Overall, 179 studies fit our inclusion criteria, with 48 on Mfx, 34 on AOT, 54 on OCA, and 51 on ACI. The rate of return to play was reported as high as 88.2% with AOT, and as low as 77.2% following OCA, with rates of return to play at the same/higher level as high as 79.3% with AOT, and as low as 57.3% following ACI. The average reported time of return to play was as low as 4.9 months with AOT, and as high as 11.6 months following ACI. CONCLUSIONS:The majority of patients are able to return to play following cartilage restoration procedures in the knee, regardless of surgical procedure utilized. However, while the rate of return to play at the same level was similar to the overall rate of return following AOT, there was a large number of patients unable to return to the same level following Mfx, OCA, and ACI. Additionally, there is wide variety in the rehabilitation protocols, and scant literature on return-to-play protocols.

PURPOSE/OBJECTIVE:The purpose of this study is to present one institution's experience managing chronic exertional compartment syndrome (CECS) and to identify patient and surgical characteristics associated with better outcomes following open surgical management of CECS with specific emphasis on return to sports. METHODS:Fifteen patients (10 male, 5 female) who underwent open fasciotomy for CECS with a minimum of 1-year follow-up were included. Chart review was performed to obtain patient demographics, medical and surgical history, presenting symptomatology, and surgical details of fasciotomy. Outcomes were assessed using follow-up questionnaires that consisted of Tegner Activity Scale, EuroQol-5D (EQ5D) index score, EQ-5D rating scale, symptom resolution, patient satisfaction, and return to sports. RESULTS:The mean patient age at the time of surgery was 28.1 years (range: 17 to 49 years). At mean follow-up of 2.7 years (range: 1.0 to 5.1 years), five patients reported complete resolution of symptoms, eight reported improvement (but not resolution) of symptoms, one reported no change in symptoms, and one reported worsening of symptoms. The mean Tegner Activity Score was 6.7 (range: 1 to 9) prior to injury and 4.7 (range: 1 to 9) postoperatively. Patients with any preoperative symptoms at rest had significantly lower Tegner before score (4.0 vs. 7.1, p = 0.036) and EQ5D rating (50.0 vs. 83.5, p = 0.04) compared to those that only experienced symptoms with activity. Patients that had prior surgery, including fasciotomy, had significantly lower EQ-5D rating than patients with no history of prior lower extremity surgery (56.7 vs. 84.6, p = 0.045). Although 10 (66%) patients were able to return to sports, only four (27%) of them were able to return to their prior level of sport. The overall satisfaction rate was 87%. CONCLUSION/CONCLUSIONS:Although open surgical fasciotomy for treatment of chronic exertional compartment syndrome leads to high rates of symptom improvement or resolution, fewer patients are able to return to their prior level of sports. Presence of symptoms at rest, presence of bilateral symptoms, and history of prior lower extremity surgery all portend worse outcomes.
